Sorry for the delay, you just missed me.

I'm seeing the slowness right away, when the rsync starts.  I'm seeing
bursts of traffic where I see a packet from download.fedora (with one
file listing), I ack it, repeat for several packets.  Then I see a delay
from download.fedora for some multiple of 20 seconds, usually 1 or 2.
Then another burst of packts.  I've seen no retransmits, so it's not
congestion?

I'm mirroring fedora-enchilada, so it's a fairly large set.  Here's my
exclude file (old versions and the architectures my users tend not to
use.)

Nobody believed that I could build a space station here.  So I built it anyway.
It sank into the vortex.  So I built another one.  It sank into the vortex.  
The third station burned down, fell over then sank into the vortex.  The fourth
station just vanished.  And the fifth station, THAT stayed!
